Can You Use the Same Shipping Label for Multiple Packages?

It is not uncommon to ship more than one package to the same address at a time, whether you’re sending a gift, fulfilling customer orders, or moving personal belongings. This raises a practical question: can the same shipping label be used for multiple packages, or does each parcel require its own?

A shipping label is the unique identifier of a package because it contains the information the carrier needs to deliver the package to its destination. It usually includes the recipient’s and sender’s names and addresses, a barcode and tracking number, the selected shipping service, the paid postage amount, and the package’s weight and dimensions. Since shipping labels are generated when postage is purchased, they also serve as proof of payment.

Since shipping label is a unique identifier associated with a single parcel, it cannot be reused once it is scanned into the carrier’s system. But what if you have a shipment consisting of several packages that are shipped at the same time to the same address? The answer is still “no”. It is impossible to use identical copies on two or more separate packages, even if they are shipped together, for several reasons.

First, the postage you pay is based on the package’s weight and dimensions, unless it’s a flat-rate shipment. If you place copies of the same shipping label on several packages, you have underpaid. Second, carriers’ systems are designed to track a single package with a specific tracking number. If multiple packages share the same tracking number, only the first package scanned is typically processed normally.

The rest will be flagged as duplicates, which can cause problems. The carrier may return the extra packages to the sender, hold them for postage due, or hold you liable for fraud because reusing a shipping label to avoid paying postage is considered misuse.

What should you do, then, if you need to ship multiple packages to the same address? For example, a large online order split into multiple boxes or several boxes containing your belongings during a move. In such case, each package needs a separate shipping label with a unique tracking number, barcode, and postage. Even though you treat these packages as a whole, they are independent shipments for the carrier.

The USPS has an SCAN form that allows you to link several shipping labels together, so postal workers can scan all packages at once during acceptance. However, this form does not replace individual tracking numbers and labels. It only simplifies the acceptance process. While it is highly probable that the packages will travel through the network together and arrive simultaneously, the USPS will still treat them as separate shipments.

It should be noted that USPS allows you to reprint a shipping label if the original label is blurred or damaged, if you misplace the original copy before shipping, or if you want to include a backup copy in the package in case the original gets lost or damaged in transit. However, printing a second copy does not create a new shipping label with a unique tracking number.

What would happen if you accidentally used an extra copy of an existing shipping label on another package? The possible outcome depends on when the error is discovered. If the first package has been accepted by the carrier, the second will likely be rejected because the tracking number is already in the system.

If the package with the duplicate label is accepted, it may get lost, returned to the sender, or delayed while the shipment is investigated for suspected mail fraud. Even if the carrier concludes that you reused the shipping label unintentionally, you will have to pay postage to have the package delivered.
